The color carrier is removed out of a CVBS signal by means of a notch filter. It is set to
the corresponding color carrier (3.58 or 4.4 MHz) only if the standard is detected
permanently. This prevents the luminance sharpness of being changed within the
standard search process. For Y signals the notch is disabled.
For a fine adjustment of delaycompensation between luminance and chrominance,
YCDEL allows a luminance shifting in 16 steps of 50ns.

Luminance and chrominance signals are filtered in horizontal and vertical direction. The
coarse horizontal and vertical picture size (1/2, 1/3, 1/4, 1/6) is independently
programmable with SIZEHOR and SIZEVER. A fine adjustment in steps of 4 pixel and 2
lines is possible by HSHRINK and VSHRINK, which allows correct aspect ratio for
multistandard applications (50/60 Hz mixed mode, (S)VGA).
For main decimation factors, the stored number of pixel and lines are listed in the
following tables.
